Abstract Indonesia has high level of seismic activity, so determining magnitude an earthquake is important in the Earthquake Early Warning System. In System, parameter must be estimated earlier, that warnings can disseminated before S and surface waves arrive. previous studies machine learning technology used to recognized events extract hidden information with massive datasets. This study was ...

It has been suggested that differences in performance on number-line estimation tasks are indicative of fundamental differences in people's underlying representations of numerical magnitude. However, we were able to induce logarithmic-looking performance in adults for magnitude ranges over which they can typically perform linearly by manipulating their familiarity with the symbolic number forma...

Instead of pilot tones, the impulse sample is exploited for channel estimation in Impulse Postfix OFDM systems [1]. As the magnitude of impulse sample is increased, the accuracy of channel estimation can be enhanced, but it may significantly increase the PAPR of generated OFDM symbols. In this letter, based on the statistical analysis of the generated OFDM symbol, we propose a decision scheme f...

Development of estimation has been ascribed to two sources: (1) a change from logarithmic to linear representations of number and (2) development of general estimation skills. To test the representational change hypothesis, we gave children and adults an estimation task in which an automatic, linear representation is less adaptive than the logarithmic representation: estimating the value of sal...

Sequential effects are examined in four successive ratio estimation (RE) experiments. The procedure in successive RE is identical to that for magnitude estimation (ME), but the task in successive RE is to estimate the ratio of the current to the previous sensation magnitude, and not the separate magnitudes of the sensations. A positive stimulus context effect was found in successive RE for seve...
